Adding romosozumab to estrogen therapy for low bone mass in young women with lost periods

Romosozumab as an adjunct to physiologic estrogen replacement in adolescents and young adults with functional hypothalamic amenorrhea

NIH-funded research Massachusetts General Hospital · NIH-11317011

Monthly romosozumab injections combined with estrogen patches aim to help build bone in adolescents and young adult women with functional hypothalamic amenorrhea.

What this research studies

You would be randomly assigned (more likely to get the active drug than placebo) in a double-blind trial that lasts about 12 months. For the first 6 months you would get monthly injections of romosozumab or matching placebo while wearing a transdermal estradiol patch and taking calcium and vitamin D; at month 6 everyone receives a single intravenous dose of zoledronic acid to help consolidate gains. The study measures bone mineral density, bone structure scans, and blood markers to see how your bones respond. About 84 participants will be enrolled and the team will use DXA, high-resolution peripheral CT, and computer-based strength modeling to track changes.

Who could benefit from this research

Good fit: Adolescent and young adult females with functional hypothalamic amenorrhea (for example from anorexia nervosa or exercise-related amenorrhea) who have low bone mass and are candidates for estrogen replacement are the intended participants.

Not a fit: People who have normal menstrual function, older adults who have already reached peak bone mass, those who cannot take estrogen or romosozumab, or those who are pregnant or breastfeeding would not be expected to benefit from this trial.

Why it matters

Potential benefit: If successful, the approach could increase bone mass and improve bone strength in young women with FHA, potentially reducing future fracture risk.

How similar studies have performed: Romosozumab has reliably increased bone density and reduced fractures in postmenopausal osteoporosis, but using it to boost bone accrual in adolescents and young adults with FHA is a new and relatively untested approach.
